Hyper-V

Reactions to VMware’s VSphere 4

Posted on Updated on

I was impressed with the VMware simulcast this morning announcing VSphere, the next iteration of their enterprise virtualization platform, dubbed the first “Cloud OS.” Having deployed and administered VMware products for several years, it’s exciting to see them continue to push the evolution of virtualization, which has now expanded from a single server up to multiple data centers.

It’s also becoming quite apparent that a loose alliance is coalescing between several of the established leaders in the infrastructure space. In particular, VMware continues to align with Cisco, whose recent unveiling of a “Unified Computing System” combined with VSphere offers the promise of a private “cloud in a box.” Other members of this confederation are Intel, whose recent Xeon 5500 Nehalem chip is tailored for VM loads, in addition to EMC, whose updated Symmetrix SAN is optimized for VMware and Microsoft Hyper-V support. Dell appears to be more closely aligned than HP, and has a better position in the SMB market.

And don’t count out Oracle / Sun, one of today’s VSphere demo’s featured Sunfire servers, and when Cisco CEO John Chambers left the stage to congratulate VMware’s lead engineering team, Sun racks were featured quite prominently.

So who’s not joining the party, yet?

Here’s my list –

  • HP – not seeing innovation, very quiet these days
  • IBM – passed on Sun, noticeably low-key at today’s VSphere event
  • Google – how long before they offer a full-blown Cloud service
  • Microsoft – no support for Hyper-V in VMware VSphere
  • Citrix – falling further behind, no support from EMC Symmetrix, or VSphere

The continued limited inter-operability between major virtualization vendors – VMware, Microsoft, Citrix – and subsequent “vendor lock-in” really makes me wonder about the feasibility and likelihood of a truly Open Cloud platform, given the symbiotic relationship between Virtualization and Cloud computing.

P.S. I still think Cisco should have picked up Sun…

Strange bedfellows – Microsoft and Red Hat partnership

Posted on Updated on

This announcement really caught my eye. Essentially, Microsoft and Red Hat have agreed to mutually support each other’s operating systems on their emerging virtualization platforms. Thus, Microsoft Hyper-V will support Red Hat Enterprise Linux (RHEL) 5, and Red Hat Enterprise virtualization will support Windows 2003, 2008 and so on. The timing of the announcement, last Monday February 16 which was a national holiday, was probably more than coincidental in order to lower the profile of the partnership. These two companies are not known to be friendly with each other, with Red Hat firmly established as the leading commercial vendor in the Linux market that competes fiercely with Microsoft’s Windows Server offerings. In fact, at SCaLE( Southern California Linux Conference) this past weekend, there was no mention or discussion of this announcement anywhere.

I recall testing an early release of Microsoft’s Virtual Server, the precursor to Hyper-V, several years ago and observing that the only non-Microsoft OS officially supported was SUSE Linux. Given that Red Hat and Ubuntu dominate the lion’s share of the Linux market, with SUSE a distant third, I was less than excited about Microsoft’s “cross-platform” support. Contrast this with VMware’s native support of Ubuntu, RHEL, OpenSUSE, in addition to Windows, Novell and Solaris. VMware’s competitors continue to maneuver for position, including Citrix recently offering the Xen hypervisor for free, along with enhanced coordination with Microsoft. But VMware is still leading the pack, and they’re not sitting still.
